Strange question but I heard it brought up during a discussion and I was very curious what compiler people think about it.
The question is, instead of using a virtual method table would it be feasible to use a case statement on the real class type and make a dispatch routine for each method call? For example assume “type” is the internal type of the class (where a VTable would be) and a call to “animal.DoSomething()” is called which would internally basically be this dispatch table: case animal.type of TDog: TDog(animal).DoSomething; TCat: TCat(animal).DoSomething; TMouse: TMouse(animal).DoSomething; end; The reason this was brought up was because virtual methods can’t be inlined and this would allow that but I think there would be more overhead overall to have all these case statements on every virtual method call.
